Lump behind ear more like a bone growth than flesh
I have never had it examined and I have never taken it to anyone.its about the size of a nickel in circular size but its not like a lump like how you would call a horn under the skin as its rounded top gets wider and flattens onto the side of my skull.. its been there since I can remember and I cannot remember a time I did not have it but I also am worried it could be something bigger but as I said it still and never has caused any form of problems no pain no irritations... besides sunglasses.. and I have no other protrusions on my body however I would like to know what this is or could be and if you have any ideas please tell me:)
